STEPHEN Hamilton, chief executive of beleaguered green power company Icon Energy, will tell customers on Monday whether he has found a buyer for the business.  Kinross-based Icon, which sells and installs wind turbines, was forced into voluntary liquidation after ayshire turbine manufacturer Proven Energy fell into receivership following the discovery of a potential fault in one of its models. Icon had attempted to buy Proven with the support of local MSP Roseanna Cunningham but lost out to Irish group Kingspan.  Mr Hamilton has said he is hoping to find a buyer for Icon, which has 35 employees. The company s predicament has also caused consternation among customers, many of whom are farmers, who put down five-figure deposits for a turbine.
